Abstract

Active Interference Arc Suppression Device（AIASD）has strong arc suppression ability and is an effec-tive arc suppression method. Isolated neutral system has good operation stability

however

the fault line selection ac-curacy of AIASD in isolated neutral system still needs to be improved. Aiming at the fault line selection problem ofAIASD in isolated neutral system

the principle of AIASD is analyzed and the characteristics of zero-sequence cur-rent amplitude and phase are considered

and the fault line selection method based on vector difference of zero-se-quence current is proposed. Fault simulation analysis is conducted on PSCAD/EMTDC

and the results prove the ac-curacy of the proposed method.
